Abstract

A swept laser source at center wavelength of 1060 nm for Fourier domain optical coherence tomography (FDOCT) was demonstrated. The laser is composed of a fiber-coupled SOA gain module, a fiber Fabry-Perot tunable filter, fiber isolators and couplers to form a ring laser. The laser is capable of a scanning range of 64 nm and coherence length of 9.8 mm at 2 KHz sweep rate. With the built swept source, a FDOCT system was developed which can achieve 12 &mgr;m axial resolution in tissue. Imaging of pig retina was demonstrated with the FDOCT system.
